  1. Hello Ferra, 
    Thank you so much for your article on mental disorders. This is something that is often mislooked in our society (at least for my country), and I really do appreciate your write up on this topic. A lot of people in my country often think that victims of mental disorders are always purposely ‘acting it out’ to get attention from others which I strongly disagree. This happens when people are not educated about mental health and have a weak knowledge about these issues. Your article will be great at not only helping those in need of answers but also help to educate people around the world on this issue. I really did enjoyed my read on your article, as it has such a clean structure which makes it so easy to read and understand. Your article is also accompanied by a lot of pictures, which helps in making the website more interactive and it’s also a great way to attract your viewers and have a more interactive website. Your attention to detail in every type of the mental disorder that you have mentioned shows that you great knowledge on the topic and have done an intensive research on it as well. All in all, a great article with a great purpose. Keep it up and well done!

  3. Hi Ferra,

    Thanks for this eye opening article. I am truly amazed at the diversity of mental disorders. The interesting thing is that those who are affected rarely recognize the fact that they have a disorder – or end up being in denial.

  4. This is quite a great post that is filled with so much information and a very well enlightenment. I personally found this to be worthwhile and worth reading. Many people have exhibited these traits without them knowing that there is any problem with their mental capacity, however they can get to discover later on. In fact, I have seen people who thinks that’s how they have always been without seeking medical help. This is dangerous and also very bad.

    Thanks for this post.
